PRIORITY

This application is a continuation of pending U.S. application Ser. No. 13/856,968 filed on Apr. 4, 2013. The contents of this document are hereby incorporated by reference herein.

TECHNICAL FIELD

The present disclosure relates to communication networks and, more particularly, to allocation of bandwidth for communicating content files in a communication network.

BACKGROUND

Content owners may have one or more files that they need to transfer from one location to multiple other locations, which may be geographically distinct. For example, a news reporter may record a segment for presentation on a nightly news broadcast at several locations around the country. Conventional file distribution systems generally use “best effort” communication schemes, which can result in a random distribution of files without taking into account user preference or destination priority. In the case of the news reporter application, for example, it may be more critical to get the recorded news segment to television stations on the east coast than it is to get the recorded news segment to television stations on the west coast due to the time difference between the different geographic locations. Without the ability to prioritize based on destination, however, communication resources, such as bandwidth, may not be efficiently allocated in distributing content files. Files may reach lower priority destinations at the same time or earlier than higher priority destination with no benefit to the early arrival at the low priority destinations, but potential negative repercussions for a late arrival at a higher priority destination.

SUMMARY

Some embodiments of the inventive subject matter are directed to a method for communicating content files based on destination priority. The method includes processing a content file to determine a plurality of destination sites to which the content file is to be transmitted, assigning priority levels to the plurality of destination sites, allocating a plurality of bandwidth portions on a communication link to the plurality of destination sites, respectively, based on the priority levels assigned to the plurality of destination sites, and transmitting the content file to the plurality of destination sites using the plurality of bandwidth portions allocated to the plurality of destination on the communication link, respectively.

Advantageously, embodiments of the present inventive subject matter may allow for bandwidth on an outgoing communication link to be partitioned based on priority levels assigned to various destination sites so that higher priority destinations may receive a greater share of the available bandwidth relative to lower priority destinations. As a result, content delivery can be better tuned to satisfy user needs as opposed to delivering the content randomly without regard to the priorities or needs associated with the various destination sites. Moreover, by prioritizing delivery of content based on destination and, for example, specifying a time that content needs to reach a destination site, embodiments of the present inventive subject matter may dynamically adjust the use of outgoing bandwidth to deliver the content by the specified time. This may reduce the need for human monitoring and auditing to ensure that content files reach destination sites in a timely manner.

The priority levels may be assigned to the different destination sites based on various criteria including, but not limited to, the geographic locations of the destination sites, the subject matter contained in the content file, an agreement with an entity associated with one of the destination sites, such as a financial agreement, a transmission speed of a destination network associated with a destination site, and/or a file format associated with the content file.

In other embodiments, assigning the priority levels to the plurality of destination sites includes identifying a time by which the content file is to reach one of the plurality of destination sites, determining a size of the one of the plurality of bandwidth portions associated with the one of the plurality of destination sites based on the time that was identified, and assigning the priority levels based on the size of the one of the plurality of bandwidth portions that was determined.

In still other embodiments, the method further includes maintaining a queue comprising a plurality of content files and prioritizing the plurality of content files for transmission. The content file to be communicated to a destination site is the content file in the queue having the highest priority for transmission.

Other methods, apparatus, and computer program products according to embodiments of the inventive subject matter will be or become apparent to one with skill in the art upon review of the following drawings and detailed description. It is intended that all such additional methods, apparatus, and computer program products be included within this description, be within the scope of the present invention, and be protected by the accompanying claims. Moreover, it is intended that all embodiments disclosed herein can be implemented separately or combined in any way and/or combination.

DETAILED DESCRIPTION

The invention will now be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Some embodiments are directed to content file distribution where a communication network resource, such as bandwidth, is allocated based on priority levels assigned to various destination sites for the content file. A content file may be processed to determine which destination sites the file is to be transmitted to. Priority levels may be assigned to the various destination sites and the outgoing bandwidth on a communication link to the destination sites may be partitioned based on the priority levels assigned to the various destination sites. The content file is then transmitted to the various destination sites using the bandwidth portions allocated to the different destination sites, respectively.

The priority levels may be assigned to the different destination sites based on various criteria including, but not limited to, the geographic locations of the destination sites, the subject matter contained in the content file, an agreement with an entity associated with one of the destination sites, such as a financial agreement, a transmission speed of a destination network associated with a destination site, and/or a file format associated with the content file. The priority levels may also be assigned to the destination sites by specifying a desired time that the destination file should reach a destination site and determining the size of the bandwidth portion associated with that destination site based on the time that was specified. Thus, if it is desired that a content file reach a particular destination site in a short amount of time, increased bandwidth can be allocated to the communication link for transmitting the content file to that particular destination site. Embodiments of the present inventive subject matter may, therefore, allow for bandwidth on an outgoing communication link to be partitioned based on priority levels assigned to various destination sites so that higher priority destinations may receive a greater share of the available bandwidth relative to lower priority destination so that content delivery can be better tuned to satisfy user needs as opposed to delivering the content randomly without regard to the priorities or needs associated with the various destination sites.

FIG. 1 is a block diagram of a communication network 100 for communicating content files based on destination priority according to some embodiments of the inventive subject matter. The communication network 100 includes a content owner that creates a content file using, for example, a recording device 105. The content file may be communicated via satellite 110 through a base station 115 to a content server 120 for distribution to a plurality of destination sites 135 a, 135 b, and 135 c. The content server 120 is connected to the plurality of destination sites 135 a, 135 b, and 135 c via a network 130. The network 130 may be a global network, such as the Internet or other publicly accessible network. Various elements of the network 130 may be interconnected by a wide area network, a local area network, an Intranet, and/or other private network, which may not be accessible by the general public. Thus, the communication network 130 may represent a combination of public and private networks or a virtual private network (VPN). The network 130 may be a wireless network, a wireline network, or may be a combination of both wireless and wireline networks. The content server 120 further includes a bandwidth allocation module 125. The bandwidth allocation module 125 may be configured to assign priority levels to the various destination sites 135 a, 135 b, and 135 c and to allocate portions of the outgoing bandwidth from the content server to the various destination sites based on the assigned priority levels.

Although FIG. 1 illustrates an exemplary communication network according to some embodiments of the inventive subject matter, it will be understood that the present invention is not limited to such configurations, but is intended to encompass any configuration capable of carrying out the operations described herein.

FIG. 2 illustrates a data processing system 200 that may be used, for example, to implement the content server 120 of FIG. 1 and may include a bandwidth allocation module, in accordance with some embodiments of the inventive subject matter. The data processing system 200 comprises input device(s) 205, such as a keyboard or keypad, a display 210, and a memory 215 that communicate with a processor 220. The data processing system 200 may further comprise a storage system 225, a speaker 230, and an I/O data port(s) 235 that also communicate with the processor 220. The storage system 225 may include removable and/or fixed media, such as floppy disks, ZIP drives, hard disks, or the like as well as virtual storage such as a RAMDISK. The I/O data port(s) 235 may be used to transfer information between the data processing system 200 and another computer system or a network (e.g., the Internet). These components may be conventional components, such as those used in many conventional computing devices, and their functionality, with respect to conventional operations, is generally known to those skilled in the art. The memory 215 may be configured with a bandwidth allocation module 240 that may be used to allocate the bandwidth on an outgoing communication link to content destination sites based on relative priorities assigned to the destination sites.

FIG. 3 illustrates a processor 300 and memory 305 that may be used in embodiments of data processing systems, such as the data processing system 200 of FIG. 2, for communicating content files based on destination priority in accordance with some embodiments of the inventive subject matter. The processor 300 communicates with the memory 305 via an address/data bus 310. The processor 300 may be, for example, a commercially available or custom microprocessor. The memory 305 is representative of the one or more memory devices containing the software and data used for allocating bandwidth in accordance with some embodiments of the inventive subject matter. The memory 305 may include, but is not limited to, the following types of devices: cache, ROM, PROM, EPROM, EEPROM, flash. SRAM, and DRAM.

As shown in FIG. 3, the memory 305 may contain up to five or more categories of software and/or data: an operating system 315, a destination priority level assignment module 330, a destination bandwidth allocation module 335, a content files queue 340, and a communication module 345. The operating system 315 generally controls the operation of the data processing system. In particular, the operating system 315 may manage the data processing system's software and/or hardware resources and may coordinate execution of programs by the processor 300. The destination priority level assignment module 330 may be configured to assign relative priority levels to various destination sites for delivery of one or more content files. The destination bandwidth allocation module 335 may be configured to allocate the bandwidth to the various destination sites on an outgoing communication link based on the relative priorities assigned to the destination sites. The content files queue 340 may represent a queue where content files are stored while awaiting transmission on an outgoing communication link. The content files in the queue may be assigned various transmission priorities relative to each other. The next file to be transmitted on an outgoing communication link may be the content file with the highest relative transmission priority in the queue 340. The communication module 345 may be configured to manage the communication protocols for transmitting content on an outgoing communication link according to some embodiments of the inventive subject matter.

Although FIG. 3 illustrates exemplary hardware/software architectures that may be used in data processing systems, such as the data processing system 200 of FIG. 2, for communicating content files based on destination priority, according to some embodiments of the inventive subject matter, it will be understood that the present invention is not limited to such a configuration but is intended to encompass any configuration capable of carrying out operations described herein. Moreover, the functionality of the data processing system 200 of FIG. 2 and the hardware/software architecture of FIG. 3 may be implemented in a variety of ways including, but not limited to, a single processor system, a multi-processor system, a multi-core processor system, or even a network of stand-alone computer systems, in accordance with various embodiments.

Computer program code for carrying out operations of data processing systems discussed above with respect to FIG. 3 may be written in a high-level programming language, such as Python, Java, C. and/or C++, for development convenience. In addition, computer program code for carrying out operations of the present invention may also be written in other programming languages, such as, but not limited to, interpreted languages. Some modules or routines may be written in assembly language or even micro-code to enhance performance and/or memory usage. It will be further appreciated that the functionality of any or all of the program modules may also be implemented using discrete hardware components, one or more application specific integrated circuits (ASICs), or a programmed digital signal processor or microcontroller.

Operations of a communication network for communicating content files based on destination priority will now be described with reference to the flow charts of FIGS. 4 and 6-9 and the network diagram of FIG. 5. Referring now to FIG. 4, operations begin at block 400 where the destination priority level assignment module 330 determines which sites a content file is to be communicated or transmitted to. At block 410, the destination priority level assignment module 330 assigns relative priority levels to the different destination sites that were identified at block 400. The destination bandwidth allocation module 335 partitions the bandwidth of an outgoing communication link at block 420 such that portions of the bandwidth are allocated to the different destination sites for the content file based on the priority levels assigned at block 410. The content file is then transmitted or communicated to the various destination sites at block 430 via the communication module 345 and using the bandwidth portions allocated at block 420.

FIG. 5 is a diagram of a communication network illustrating operations for communicating content files based on destination priority according to some embodiments of the inventive subject matter. A content server 505 is connected to a network 520 via a 30 Mbps communication link. The content server 505 includes one or more content files 510 to be communicated to a plurality of destination sites 525 a, 525 b, 525 c, 525 d, 525 e, and 525 f. The network 520 may be a global network, such as the Internet or other publicly accessible network. Various elements of the network 520 may be interconnected by a wide area network, a local area network, an Intranet, and/or other private network, which may not be accessible by the general public. Thus, the communication network 520 may represent a combination of public and private networks or a virtual private network (VPN). The network 120 may be a wireless network, a wireline network, or may be a combination of both wireless and wireline networks.

As shown in FIG. 5 destination sites three and four have been assigned a priority level of four, destination sites one, four, and five have been assigned a priority level of two, and destination site six has been assigned a priority level of one. Thus, destination sites three and four are each allocated a 4/15 share of the 30 Mbps bandwidth of the outgoing communication link for communicating one or more of the content files 510, destination sites one, four, and five are each allocated a 2/15 share of the 30 Mbps bandwidth for communicating one or more of the content files 510, and destination site six is allocated a 1/15 share of the 30 Mbps bandwidth for communicating one or more of the content files 510. The destination sites 525 a, 525 b, 525 c, 525 d, 525 e, and 525 f may have particular download bandwidths associated therewith as shown in FIG. 5, which may be a factor in assigning priorities in bandwidth allocation outgoing from the content server 505. For example, if a destination site has a very high bandwidth pipe for downloading content, then it may be assigned a lower priority level in allocating bandwidth outgoing from the content server 505 because the destination site may make up for the lower transmission bandwidth with a higher download speed.

Referring now to FIG. 6, at block 600 the destination priority level assignment module 330 assigns priority levels to the various destination sites to which the content file(s) are to be communicated based on criteria including, but not limited to, geographic locations of the destination sites, the subject matter contained in the content file(s), an agreement with an entity associated with a destination site, e.g., a financial agreement ensuring a minimum bandwidth allocation, the transmission or download speed of a network associated with the destination site(s), and/or a file format associated with a content file, e.g., it may be desirable to communicate a low resolution file quickly and follow up with a higher resolution version (block 610).

Referring now to FIG. 7, as described above with reference to FIG. 3, content files may be maintained in a queue 340 at block 700. The content files in the queue 340 may be prioritized for transmission at block 710 using the destination priority level assignment module 330 such that the content file selected for communication from the queue 340 is the content file having the highest relative transmission priority relative to the other content files in the queue. In accordance with various embodiments of the inventive subject matter, the content files buffered, for example, in the content files queue 340 of FIG. 3 may include, but are not limited to, video files, audio files, voice files, and/or text files.

Referring now to FIG. 8, at block 800 content files may be prioritized for transmission using the destination priority level assignment module 330 based on criteria including, but not limited to, file formats associated with the content files, e.g., it may be desirable to communicate a low resolution file quickly and follow up with a higher resolution version and/or the subject matter contained in the content files, e.g., is the subject matter associated with a real time event (block 810).

According to other embodiments of the inventive subject matter illustrated with respect to FIG. 9, a target time may be specified by which a content file is to reach a particular destination site at block 900. The target time may be received, for example, from a user or administrator and received via the operating system 315 utilities for handling input/output operations. The destination bandwidth allocation module 335 may then determine the size of the bandwidth needed to be allocated to the particular destination site on an outgoing communication link of the content server to communicate the content file to the destination site in the specified time at block 910. The destination priority level assignment module 330 may then assign priority levels to the various destination sites at block 920 to ensure that the bandwidth allocated to the destination site having the specified arrival time for the content file is sufficient to allow the content file to arrive on time. Thus, if target times have been specified for various content files, the content server may assign relatively low priority values to destination sites to receive small files with far off arrival times and relatively high priority values to destination sites to receive larger files with near term arrival times.

Embodiments of the present inventive subject matter may allow for the ability to prioritize delivery of content based on the destination. This may allow for file owners and/or communication network owners/operators to more efficiently use the resources of the communication network. In addition, by prioritizing delivery of content based on destination, there may be less need for human monitoring and auditing to ensure that content files reach destination sites in a timely manner.
